Well, certainly Jack O'Connor thought highly of "the little 7mm." I recently came across a 1974 Gun Digest article by O'Connor entailing the history of and his experience with the 7x57.
He mentioned his first purchase in 1934 of a rifle in that caliber, a Mauser 98 actioned custom by gunsmith Bill Sukalle of Tucson with stockwork by Adolph Minar. O'Connor had a Noske 4x fieldscope mounted in a Noske sidemount and the rifle weighted in at under 8 pounds. He regretted trading off that "lovely little" rifle in 1940 and mentioned praise for the cartridge from hunters such as his wife Eleanor, W.D.M. Bell, Capt. Jim Corbett and Prince Abdorreza of Iran.
This statement from O'Connor says it all. "I think I've seen more game killed with fewer shots from this modest little cartridge than any other." High praise indeed!
